Just wondering if anyone has used this additive to their tanks. I saw it for the first time at the campground store at Carter Lake and then again at the RV store in a larger bottle and this is the first time i've heard of it. So I picked up a pamphlet the other day while visiting an RV store and read it over and it sounds like a good idea and that it would work, but I'd like to hear some feedback from some people who have actually used it. It claims that 2oz's of it will treat a 40 gallon tank and it won't freeze and does not contain formaldehyde. It's made by Unique manufacturing & marketing and they're out of Arvada, Colorado. Website is www.uniquemm.com . Who's heard of it and used it?

We use Unique Digest it. It is what came with our first TT and we were also told it was a good product by the dealer who sold us the second. Seems to work well with only 2 oz. We however don't have experience with freezing being in Florida

Thanks for the info. I am preparing myself for next year's trips and the idea of having to deal with the waste water tanks in general. Part of me is not looking forward to it at all, so anything I can do to help alleviate the "pain and suffering" of dumping our own waste will be very helpful. I've already purchased a tornado kit and I will probably install it sometime next year before the season starts, but after it warms up again so that i can rinse and drain anything left over in the tanks from the previous owners (hopefully that's nothing) before drilling the holes in the tanks. I have read several people using things like Calgon with great success in keeping down the odors and keeping the tanks cleaned out, so i'll probably follow some of that advise as well. If this Unique product works like it says, i'll give it a whirl at some point. I think once i figure out how to best deal with the tanks, it won't be so bad. After all, why have it if you're not going to use it....Right?
